限界があった。[Problems to be Solved by the Invention] However, when dyes are used as coloring materials in inkjet printing using hot melt inks as described above, dye solubility is not necessarily excellent, and the type of dye Further, they are not necessarily stable against long-term heating or repeated heating and cooling, and also have problems in light fastness. In addition, regardless of whether dyes or pigments are used as the coloring material, with conventional hot melt inks, the size of the recording dots formed by ink droplets on recording paper depends on ink properties such as ink viscosity and surface tension. This is determined by device characteristics such as the orifice diameter, ejection force, and ejection temperature of the ink ejection device, and there is a limit to the improvement in recording density.

ある。The vehicle in this example is paraffin wax HNP-10 manufactured by Nippon Seiro Co., Ltd., and the pigment is
It is carbon black. Additionally, EVA210, an ethylene-vinyl acetate copolymer manufactured by Mitsui Polychemical Co., Ltd., is added to give the ink adhesive strength to the recording paper. The composition of the ink used in this example is as follows.

Preparation of 5 wt% ink was performed by first adding the HNP-10
and the EVA210 are heated and melted and mixed in the same container, and then the carbon black is added and dispersed using a grinding device such as an attritor or a roll mill. At this time, the paraffin wax (HNP-10), which is a dispersion medium, does not have a polar group, so it cannot sufficiently wet the carbon black, which has polarity on its surface, and the carbon black is not completely dispersed. The result is a pseudo-dispersion state.

こるなどの問題が起こってしまうのである。In the case of this example, the average particle size of the carbon black was 5 um. What is the pseudo-dispersion state here?
This is a state in which the pigment is dispersed with a particle size of 1 um or more and 30 um or less, and when this pseudo-dispersion state is achieved, the effect of the pigment being concentrated at the center of the printed dot is obtained. If the particle size is 1u
If it is less than 30 um, it will be difficult for the pigment to accumulate in the center of the printed dot, and if it is larger than 30 um, problems such as clogging of the orifice during ink ejection and pigment settling before ejection will occur. be.

、当然、記録密度は高くすることが可能である。When the ink obtained as described above is printed on a recording paper by an ink ejecting device, print dots 1 as shown in FIG. 1 are formed on the recording paper 3. As can be seen from FIG. 1, it is the recording dot 2 that actually functions as a recording pixel. Therefore, the recording dot 2 is smaller than the printing dot 1, and it is possible to naturally increase the recording density compared to the conventional case where the printing dot and the recording dot are the same size. It is.

能となる。When actually printing, the print feed width of the print head 4 movably supported by the shaft 6 and the paper feed width of the recording paper 3 supported on the platen 5 are determined as shown in FIG. By matching the diameter of the recording dot 2 instead of the diameter of the printing dot 1, the effect of increasing the density can be achieved. In the case of this example, it was found that the area of the recorded dots occupied about 85% of the area of the printed dots, but this area occupancy rate varied somewhat depending on the dispersion method, printing conditions, and paper quality. When the area occupancy rate is 85%, the recording density is 1.18 times that of the case where the area occupancy rate is 100%. By using an ink having the composition shown in the example, it is possible to increase the recording density up to 350 dpi.
